Speed Wedge MKII Radar sensor

Product Overview

Speed measurement for in-door and off-highway vehicles, conveyor belts, material flow

Speed Wedge MKII true ground speed sensor

Speed Wedge MKII is a speed sensor for moving objects, based on Radar Doppler technology. Speed Wedge MKII deploys a Radar Frontend with planar antennas. The forward speed is measured contactless thus unsusceptible to wheel / drive slip, effective tyre circumference and sinking in of the tyre. For demanding applications it is sealed and potted in a rugged encasing.

Speed Wedge MKII is available as prototype.

Benefits/Use

Benefits/Use

  • Measurement of speed and distance travelled independent on wheel / drive slip
  • High dynamics and signal update rate
  • Easy installation in parallel to the object being measured
  • Unsusceptible against pitch, yaw and roll of the vehicle
  • Unsusceptible against varying properties of the ground surface
  • Pulse Output according to DIN 9684 / ISO 11786, optional serial RS232
  • Basis for precise output application
